摘要 目的对罗氏Cobas E601全自动电化学发光免疫分析仪检测3种糖类抗原CA125、CA153和CA199的分析性能进行验证。方法对3种糖类抗原的精密度、准确度、测量线性范围、参考区间和携带污染率进行验证实验。结果 3种糖类抗原批内精密度变异系数(CV)高低值分别为4.80%和3.74%,日间精密度CV高低值分别为4.86%和3.93%;5份室间质控品的检测结果与靶值的偏倚在-6.12%~6.4%之间;测量线性范围与厂家提供的范围相近;CA125和CA153的测量数值100%在提供的参考区间内,CA199的测量数值有98.3%在参考区间内;携带污染率范围为0%~0.18%。结论罗氏COBAS E601检测糖类抗原CA125、CA153和CA199的方法学性能良好,能够为临床提供准确可靠的检验结果,满足临床检测的要求。
